A manual impact driver for aiding the removal of a threaded fastening member from a structure, is disclosed having a longitudinal axis (L), the manual impact driver including a body having a first end and a second end and a sliding member configured to be coupled to the body at the second end. The impact driver is movable between a first configuration, upon impact at the first end of the body, a linear impact force is translated along the longitudinal axis (L) from the first end of the body to the sliding member and a second configuration, upon impact at the first end, the linear impact force produces a torque, about the longitudinal axis (L), at the sliding member. The impact driver is operable to switch between the configurations upon rotation, by a user, of the body with respect to the sliding member.

A pneumatic hammer extender arm assembly is provided comprising an elongated extender arm body defining a hammer engaging portion formed at a first end of the body, and a hammerhead engaging portion formed at a second end of the body. A hammerhead is detachably engageable to the hammerhead engaging portion to allow for quick change of the hammerhead without the need for any tools. The hammerhead may alternately be implemented to engage and apply an impact force to a fastener that may be axially offset from the extender arm body.

The present utility model relates to a compression tool for applying terminals/splices attachable to an impact wrench, which, according to its characteristics, provides a compression tool (1) in its own and specific structure of universal type, attachable to an impact wrench and based on the integration of an applicator body (2), a lead screw (3) and a sliding compression die (4), so as to provide complete optimization in the set of mechanical and manual procedures for applying compression to terminals and splices of conductors of electric power distribution networks by using impact wrenches, combined with the absence of wear on conductors, terminals and splices and improvements in the maintenance of electric power distribution networks.
